About the temperature controls.
The unit will have one of the temperature controls shown below:
Internal Temperature
Controls
Internal Dial Control (0-9)
External Set Point
Controls (0-9)
The temperature controls are preset in the factory at 5 for both the refrigerator and
freezer compartments.
To adjust the set point temperature, press the WARMER or COLDER button on either the
Freezer or Refrigerator side. The set point light will come on. Press WARMER or COLDER
until the desired setting is reached.
Several adjustments may be required. Each time you adjust controls, allow 24 hours after
each adjustment for the refrigerator to reach the setting you have selected.
Setting either or both controls to 0 stops cooling in both the freezer and refrigerator
compartments, but does not shut off electrical power to the refrigerator.
Control settings will vary based on personal preferences, usage and operating
conditions and may require more than one adjustment.
NOTE: The refrigerator is shipped with protective film covering the temperature controls.
If this film was not removed during installation, remove it now.
